Using Rust Converter & Primer for Lasting Protection
After removing rust it’s important to stop it from coming back A rust converter turns leftover rust into a solid paintable layer Apply it evenly and let it dry fully Then use an automotive primer to seal the metal This protects the frame and helps the paint stick better Skipping this step means rust could return fast Using good rust converter and primer keeps your repair strong and lasting
Painting and Undercoating the Repaired Area
Once the primer is dry it’s time to paint and undercoat Use rust resistant paint made for car frames Apply several thin coats for good coverage After painting add an undercoating spray to guard against moisture salt and road grime Choose a UV resistant or rubberized undercoating for long term protection This final layer prevents rust and keeps your frame looking solid
